| Source measurement | The antenna uses phase-frequency electronic scanning technology , forming sharp 3D pencil beams covering large surveillance and track volume. It uses a rotating platform with a high scan rate (30 RPM) to provide 360 degree coverage. The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM).[source]AN/MPQ-64 Sentinel · Main characteristics; only the objects and conditions stated in this passage The system can be deployed using HMMWV fitted with a 10 kW 400 Hz 115/200 VAC on-board power generator. It can be operated autonomously and communicate with the fire direction center via wideband fiber-optic link. It can also distribute its data over a SINCGARS radio network.[source]AN/MPQ-64 Sentinel · Main characteristics; only the objects and conditions stated in this passage AN/MPQ-64A3 is mounted on a 2.5 ton trailer with an on-board power generator, towed by an armored Family of Medium Tactical Vehicles (FMTV) truck.[source]AN/MPQ-64 Sentinel · AN/MPQ-64A3 Enhanced Sentinel; only the objects and conditions stated in this passage | — |
